The Happy Line was designed for older toddlers / preschoolers that are 2+ years of age. At this age they are eating more balanced foods at mealtime (the Happy Mat is portion-sized at 4oz, 4oz and 10oz).
In addition, around this time parents should layer a new tool into their child's mealtime repertoire - a training knife! This set includes a training knife and more advanced spoon / fork with a slightly elongated handle sized for preschoolers' hands.
The set also includes the Happy Cup + Straw System, which is sized at 8oz and includes a longer and more advanced straw for enhanced swallowing skills.
